No Java compiler available for configuration optio

I am trying to make simple MVC application using Spring Boot. Everything works fine when I use simple Rest controller but doesn't work to simple controller when I try to redirect to JSP page. This is my POM:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </dependencies>

            </plugin>
        </plugins>
    </build>
</project>

This is the error:

I have seen a lot of places on internet where this is mentioned that using below dependency would work, but unfortunately it doesn't work for me.

org.eclipse.jdt.core.compiler

Any idea what can be the reason?

Adding this dependency works as I reproduced same scenario on multiple machines and this worked. Reason why this didn't work on one machine is still unknown. Most probably some configuration issues.

<dependency>
    <groupId>org.eclipse.jdt.core.compiler</groupId>
    <artifactId>ecj</artifactId>
    <version>4.6.1</version>
</dependency>
